Neodymium magnets are powerful magnets used in many different applications. Most magnets purchased from stock are nickel-plated. Nickel is an excellent choice for protecting the magnet because it is very resistant to corrosion.
Unfortunately, the same great properties of nickel which make it ideal for protecting the magnet makes it difficult for the adhesive to form chemical bonds to adhere to the substrate.
In addition, with nickel coating process creates a very smooth surface and hard, further reducing the ability of the adhesive to create a satisfactory bond with the metal.
When using neodymium magnets stock, the type of glue that actually worked very limited. The best option is a two-part epoxy adhesive.
This glue is mixed before use; create their own chemical reactions to comply with the magnet to another object.
Before attempting to glue stock Neodymium magnet, users should take the time to prepare the surface to interact with glue and create the best bond. Start by cleaning and degreasing the surface of the nickel plating. This will require the use of industrial degreaser solvents.
Household detergents and cleaners alcohol do not have the power to effectively clean and prepare it for gluing magnets. After the grease is removed, use 200-grit emery cloth to scrape the surface.
The goal is to create a surface with enough texture for the glue to grip and without breaking through nickel, which will allow the magnet to corrode.
